Where is the olfactory bulb located in the brain?

The olfactory bulb is located at the base of the frontal lobe of the brain. It is a critical structure involved in the sense of smell, as it processes olfactory information received from the sensory neurons in the nasal cavity. The olfactory bulb lies just above the nasal cavity and is directly connected to the olfactory epithelium, allowing it to play a central role in the olfactory pathway.

The proximity of the olfactory bulb to the frontal lobe is significant since it allows for a direct integration of olfactory information with higher cognitive functions, memory, and emotions, which are also associated with the frontal lobe. This anatomical positioning is essential for how we experience and interpret smells in relation to our experiences and memories.
